“…The conception rate after estrus synchronization was lower at day 25 and 45 after insemination in buffaloes in clinical (28% and 16% respectively) and subclinical mastitis (55.56% and 44.45% respectively) compared to buffaloes without mastitis (69.57% and 60.87% respectively, P < 0.05). The impact was more significant when mastitis occurred between 15 days before and 30 days after insemination, and this could be a consequence of the reduction in the diameter of the corpus luteum and the production of progesterone observed in buffaloes with mastitis [173]. In addition, parasitic gastrointestinal infection (coccidia and nematodes) reduced pregnancy rate in buffaloes treated with PGF2α or with a mix of vitamins and minerals (P < 0.05) [123].…”

“…Furthermore, the conception rate was higher in buffaloes with higher preovulatory follicles [192], and this could be explained by the positive relationship between preovulatory follicle diameter, corpus luteum diameter, and progesterone levels [192,193]. Mansour et al [173] observed positive correlations between pregnancy rate with corpus luteum diameter and progesterone concentrations at 2, 9, 12, 16, 21, and 25 days post-insemination.…”

This article aims to review both the economic impact of reproductive failures on the profitability of water buffalo systems and the effect of different factors on the reproductive performance of water buffaloes. Besides, an overview of various non-hormonal alternatives to improve reproductive performance is made. The optimal reproductive efficiency in water buffaloes implies calving to conception interval around 90 days to reach a calving interval of 400 days, with longer calving intervals having a negative impact on profitability. Reproductive efficiency is the consequence of the interaction of genetic and non-genetic factors, and the recognition of these factors by analyzing the reproductive information must be a priority. Although each factor's impact can be of greater or lesser magnitude depending on the conditions of each herd, some factors like nutrition, milk yield, body condition score, negative energy balance, parity, bull presence, low estrus intensity, and season can be considered high-impact factors. Not all factors are common among farms; therefore each farm must implement a program for the identification, control, and prevention of reproductive problems, especially during early lactation, to prevent a long anestrus; and when artificial insemination is used, so that it is done at the correct time with respect to the beginning of estrus to enhance fertility.

“…Recently, Mohsen, et al [3] investigated the relevance between animals of subclinical and clinical mastitis to pregnancy rate and embryonic loss percentage [3]. They found that the percentage of pregnancy rate (44.45%) was lower in SC mastitis affected animals as compared to normal ones (60.87%) but it was higher than the clinical mastitis affected animals (16%).…”

According to the international dairy federation, the dairy sector provides up to one billion livelihoods around the globe. Albeit, it faces many challenges including the two potentially threatening diseases which are mastitis and infertility. Both are complex multifactorial diseases, and mastitis is associated with causing infertility. Mastitis is an intramammary infection (IMI) and it occurs in two forms, clinical and subclinical. Mastitis being the infection of mammary glands, directly affects milk production to reduce its quality and quantity and indirectly hinders the reproductive performance of dairy animals. It negatively affects the reproduction parameters of dairy animals including, an increase in days open, a decrease in pregnancy rates, and increases chances of early embryonic losses and abortion. The chronic cases of mastitis lead toward the infertility of dairy animals and both of these diseases are responsible for increasing the culling rate and decreasing the profitability of a dairy farm. The objective of this study is to illustrate the influence of subclinical mastitis on reproduction parameters of dairy animals including, days open, days to the first service after calving, pregnancy rates, abortion, and embryonic losses. The relation between mastitis and infertility will be explained mechanistically. Contribution/Originality:This study contributes to the literature related to the field of animal science and particularly it discusses the issues related to subclinical mastitis in dairy animals. The primary purpose of this study is to bring this issue under the attention of animal science researchers and veterinarians to understand the gravity of situation and to work for treatment and cure of intramammary infections.Mastitis is described as the infection of mammary glands which causes physical, chemical and bacteriological changes in milk and pathological changes in mammary glands [3].
